Firefighters are getting a grip on the Klamathon Fire that's still burning near the California-Oregon border. Here's what we know as of Thursday morning.

The fire has burned 57 square miles.

The Klamathon Fire, which started July 5 off Klamathon and Copco roads near Hornbrook, is 70 percent contained as of Thursday morning, up from 40 percent on Monday. The fire's size has remained steady at 36,500 acres, and fire officials anticipate fully containing it by Sunday.

The number of structures threatened has also decreased from 1,036 to 315. Eighty-two structures have been destroyed and 12 damaged. Minimal fire activity is expected for Thursday.

The water is not safe to drink.

The Siskiyou County Office of Emergency reminded the public the water is not safe to use except to flush toilets.

“Even boiling the water will not make the water safe to drink at this time. Please do not consumer the water in any way.”

The Siskiyou County Emergency Operation Center is coordinating with the Hornbrook Water District to keep residents informed on the situation.

Some residents have gone back home.

More than 3,102 people were evacuated due to the fire, but all evacuation orders and warnings in the community of Hornbrook have been lifted.

The community, however, has no running water with no date set for when water service may be restored. All evacuation orders and warnings on the California side of the fire have been lifted, as well as in the area south of the Irongate Reservior/Klamath River and the Klamath River Country Estates.

Evacuation orders have been downgraded to a warning in the community of Colestin, Oregon and the Copco Lake area. An evacuation shelter at Jackson Street Elementary School in Yreka remains open. A large animal shelter at the Siskiyou County Fair grounds in Yreka also remains open.

The fire took a human toll.

The Klamathon Fire claimed the life of one person, whose body was found near a Hornbrook residence that was heavily damaged in the blaze. An autopsy was set for Wednesday, but authorities said it may take several weeks to conclusively determine the cause of death. So far, they have withheld releasing the person's identity.

Three firefighters also were injured in the fire, including California Department of Forestry and Fire Protection firefighter Brandon Feller, who was treated for serious burns to his face after flames overran the fire engine he was on. He since has been released from the hospital.

The cause remains under investigation.

The cause of the Klamathon Fire remains under investigation, but the California Highway Patrol has said on its website that someone reported starting a small fire on the land of a friend.

Assigned fire-fighting personnel and resources.

A total of 2,299 people are assigned to the fire, as well as 131 engines, 22 water tenders, 28 helicopters, 57 hand crews and 27 dozers. Numerous air tankers from throughout California and Oregon are flying fire suppression missions as conditions allow.
